It took four months to sail a boat made of discarded plastic bottles from San Francisco to Australia. The catamaran was built with 12,500 recycled plastic bottles and a fully recyclable plastic material called Seretex and held together with organic glue made from cashew-nut husks and sugarcane. The bottles were packed into the Plastiki’s pontoons in a pomegranate-like structure, giving the boat 68% of its buoyancy. Rothschild’s mission to change the public’s perception of plastic continues as his team brainstorms new ways to reuse the commonly discarded material in everything from surfboards to wind turbines. Every year people are throwing away tons of waste, that can actually be used as building material. Via Time who just rewarded the 50 best inventions of 2010.
